This tutorial explains how to specify the parameters for the Au-Si MEAM potential in MD++. It starts with the parameters in pure Au and pure Si potentials, then talks about the Au-Si cross potential.

MEAM Potential for Au

We use the 'Au' potential whose parameters are originally given in M. I. Baskes, Phys. Rev. B 46, 2727 (1992), and later modified by S. Ryu, et al. Model. Simul. Mater. Sci. Eng. 17, 075008 (2009).
